Application filed February 28, 1919. Serial No. 279,902.

To all whom it may concern:

citizen of the United States of America,residing at McKees Rocks, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Sanding Devices, of which the following is a specification. V V

This invention relates to sanding devices, designed primarily for use in connection with railway locomotives, but it is to be understood that a sanding device in accord ance with this invention can be employed for any purposes wherein it is found applicable, and the invention has for its object to provide, in amanner as hereinafter set forth, a sanding device having means whereby the sand is deposited on the track rail in' very close proximity to the point where the tread of the wheel contacts with the head of the rail, under such circumstances the wheel engages the sand almost immediately after it is deposited on the track rail and skidding or slipping action is reduced to a minimum, furthermore waste of sand is prevented as the wheel contacts therewith before the sand is blown away. 7

Further objects of the invention are to provide a sanding device which is simple in its construction and arrangement, strong,

durable, efficient in its use, having means to maintain it and to restore it in and to normal position in case the discharge nozzle is shifted by an obstruction at or near the track, readily set up in operative position, and comparatively inexpensive.

With the foregoing and other objects 1n view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment.

comotive 1 and which is provided with a sand box 2. The wheels of thelocomotive are indicated at 3, 4c.

Leading from the sand box 2 is a sand dehverypipe 5 which extends to a point above the track rail 6, and extending from the pipe 5 1s asand deliverypipe 7 which terminates at a point above the track rail 6. The pipe 5 is arranged at the front of and 1n close proximity to the wheel 3, and the plpe 7 extends rearwardly and is curved around the wheel l in close proximity thereto. The pipes 3, 4: are of metal and termibody, preferably rubber, and is secured to the lower end of the delivery pipe by a clamp 8 The lower edge of the nozzle 8 is fiat throughout and directly opposes and is positioned in very close proximity to the tread of the track rail 6, as well as in very close proximity to that wheel of the locomotive with which the nozzle cooperates.

The nozzle-8 is disposed at an inclination and extends toward that wheel with which it cooperates, and arranged, as well as being secured, within the nozzle 8 is a coiled spring 9, conforming in contour to the shape of and substantially of a length equal to the length of the nozzle, as well as engaging the inner face of the nozzle.

The flexibility of the nozzle prevents the brea rage or permanent bending thereof when meeting with an obstruction and the spring 9, not only maintains the nozzle 8 in normal position, so as to deliver the sand at a point in close proximity where the wheel engages with the track rail, but also restores the nozzle to normal position in case the nozzle is shifted to one side when meeting with an obstruction.

By the employment of the nozzle as shown the sand is deposited upon the track rail at a point where it can be immediately engaged by the tread of the wheel under such condition reducing skidding or slipping of gaged by the wheel before the sand can be the wheel to a minimum, furthermore saving in sand is obtained as the latter is enblown oif the track rail.

What I claim is l. A. sanding device comprising a delivery pipe, a flexible discharge nozzle secured to the lower end of said pipe and extending toward a track rail and a wheel traveling thereon, and a coiled spring arranged within and permanently engaging said nozzle and of a length substantially equal to the length of the nozzle and providing means for maintaining the nozzle in normal position.

2. In sanding devices a flexible discharge nozzle adapted to be arranged in close proximity to a track rail, said nozzle having its lower edge flat throughout and directly opposing throughout the tread of the track rail, and coiled spring arranged within and permanently engaging the inner face of said nozzle and of a length substantially equal to the length of the nozzle.

3. In a sanding device a sand delivery pipe, a'flexible "nozzle mounted on and extended from the lower end of said pipe, a clamp for securing the upper end of the nozzle on the lower end of the pipe, and a coiled spring arranged withiir' and permanently engaging the inner face of said nozzle and extending from the lower end thereof to the lower end of said pipe.
